FAQs

Heating QuestionsWe Have Answers.

Straight from our certified heating technicians.

If your furnace is under 10 years old and this is its first major issue, repair is usually the right call. If it’s 15+ years old, requires frequent repairs, or your energy bills are climbing, replacement is often more cost-effective. Day & Nite offers free second opinions and free estimates on replacements.
A heat pump transfers heat rather than generating it, providing both heating and cooling in one energy-efficient system. The Pacific Northwest climate is ideal for heat pumps — mild winters mean they operate efficiently most of the year, and many utility companies offer rebates for installation.
Ductless mini-splits install without existing ductwork, making them ideal for older homes, additions, garages, and multi-zone setups. They’re quiet, efficient, and feature Wi-Fi control. Day & Nite offers free consultations to determine if ductless is right for your space.
A 1" thick disposable pleated filter should be replaced at least every 3 months. A 4–5" thick filter should be vacuumed every 3 months and replaced every 6–12 months depending on air quality. Regular filter changes protect your furnace and improve indoor air quality.
Yes — Day & Nite specializes in oil-to-gas and oil-to-heat-pump conversions. Converting typically lowers operating costs significantly and qualifies for utility rebates. We handle the entire process including permits and removal of your old oil system.
Yes — heating failures in the Pacific Northwest can be dangerous. Day & Nite has licensed technicians available around the clock. Call (425) 224-6452 and a live person will answer any time, day or nite.
